The winners are chosen by a fair and impartial judging panel (thereby eliminating the "popularity contest" trap some internet contests fall prey to) and Torchwood writers like aviv_b, lindenharp, evalentine99 and *cough* myself have won in the past, proving that our little fandom can take on the big boys like "Star Trek" and "Supernatural" and WIN. :) The Awards also accepts fics for "Doctor Who", "Stargate", "Firefly"/"Serenity", "X-Files", "Buffy", and "Angel", so if your fic-reading tastes are more wide-ranging, go for it. :)
Fics don't have to be new works--anything that hasn't already won is eligible. You can even nominate your own fics, as self-noms are encouraged. For more information, see the site: Wicked Awards.
